I just watched a Youtube video from another country that slow down the Coronavirus. They did the same procedures we did: social distancing, stay at home, strict hygiene rules, wash your hands, and wear face masks. However everyone wore the face mask in public. I work in the apparel manufacturing industry and we start making masks for the military. They even issued everyone in the building a face mask.
When everyone wear the face mask, we are protecting each other. The mask can even be made at home.
